RECOVERY SYSTEM OF CARBON DIOXIDE
To provide a recovery system of carbon dioxide which can recover carbon dioxide stably at high efficiency and reduce heat energy supplied from outside.SOLUTION: A recovery system 100 of carbon dioxide comprises a cement manufacturing device 10, a carbon dioxide recovery device 20, and a second heat exchanger 60. The second heat exchanger 60 performs heat exchange between an exhaust gas G1 extracted from a calciner 32 of the cement manufacturing device 10, a preheater 31, or a pipeline between the calciner 32 and the preheater 31 and introduced as an exhaust gas containing carbon dioxide into an absorption tower 21 of the carbon dioxide recovery device 20, and an absorbent L reserved in a regeneration tower 22 of the carbon dioxide recovery device 20.SELECTED DRAWING: Figure 2
【課題】二酸化炭素を安定的に高効率で回収することが可能であると共に外部から供給する熱エネルギーの低減を図ることが可能な二酸化炭素の回収システムを提供する。【解決手段】二酸化炭素の回収システム１００は、セメント製造装置１０、二酸化炭素回収装置２０、及び第２の熱交換器６０を備える。第２の熱交換器６０は、セメント製造装置１０の仮焼機３２、予備加熱機３１、又は仮焼機３２と予備加熱機３１との間の管路から抽気されて二酸化炭素回収装置２０の吸収塔２１に二酸化炭素を含有する排ガスとして導入される排ガスＧ１と、二酸化炭素回収装置２０の再生塔２２に貯留されている吸収液Ｌとの間で熱交換を行う。【選択図】図２
